1 LCMPT Library of Congress Medium of Performance Thesaurus for Music Hermine Vermeij, UCLA

2 What is medium of performance?  The instruments, voices, etc. used in the performance of a musical work  (Almost)All musical works have a medium of performance  Examples:  Beethoven’s Symphony no. 5: orchestra  Schubert’s String quintet in C major: 2 violins, 1 viola, and 2 cellos

3 How we use LCSH to record medium of performance  LCSH headings for music conflate genre/form and medium of performance  Incredibly complex rules for heading construction  For some light reading, consult H 1917.5 in the Subject Headings Manual  Examples: Orchestral music String quintets (Violins (2), viola, cellos (2))

4 What’s wrong with LCSH? Part 1 Concertos (Piano)  Denotes the genre/form (Concertos) as well as the medium of performance (Piano)  “Infers” orchestra, because most concertos are accompanied by an orchestra

5 What’s wrong with LCSH? Part 2 Quintets (Harpsichord, bassoon, flute, viola, cello)  Constructed according to complex rules: first keyboard instrument(s), then wind instruments in alphabetical order, then string instruments in score order  Text string cannot be parsed by a machine

6 What’s wrong with LCSH? Part 3 Sonatas (Flute and piano) Suites (Flute and piano) Flute and piano music  Three headings that are all for the same instrumentation  No way to retrieve all music written for flute and piano

7 What’s wrong with LCSH? Part 4 Percussion ensembles  Covers all pieces written for two or more percussionists  Very little granularity ? ? ??

8 Solution: LCGFT and LCMPT  In 2007 the Library of Congress and the Music Library Association began a collaboration to remove music genre/form terms from LCSH and add them to the Library of Congress Genre/Form Terms(LCGFT)  Medium of performance terms were determined to be separate from genre/form  New thesaurus!

9 LCGFT  Work on the music portion of LCGFT is ongoing  LC and MLA hope to have a tentative list ready by early 2015  Once ready, music LCGFT terms will be post- coordinated with LCMPT terms to replace the music LCSH headings that have been used purely for genre/form access  Subject headings that are used topically will remain in LCSH.

10 LCMPT  Released in February 2014  Over 800 terms  Generally singular, lowercase  Three top terms: ensemble, performer, and visuals  Each term has at least one broader term  Many terms have scope notes

11 Availability of LCMPT  Classification Web  As linked data (breaking news!): Download LCMPT in MARC UTF-8 format: http://classification

14 LCMPT Best Practices  Provisional best practices now available: Historical/BCC2014/ProvisionalBestPracticesf orUsingLCMPT%20FINAL.pdf  Fuller best practices will be developed once LCGFT for music is released

15 MARC coding  LCMPT terms are coded in the 382 field in both bibliographic and authority records  MLA and LC put through several MARC proposals in the last few years to massage the 382 to be more granular

16 382 overview  1 st indicator – Usually 0 for Medium of performance  2 nd indicator – Coded 1 in bib records for Intended for access  $a – Medium of performance (where most of the LCMPT terms go  $b – Soloist (when there is a featured instrument or voice)  $d – Doubling instrument (when a performer plays more than one instrument)

17 382 overview (continued)  $n – Number of performers of the same medium  $p – Alternative medium of performance  $s – Total number of performers  $v - Note

18 382 example (simple) Medium of performance: string quartet 382 01 $a violin $n 2 $a viola $n 1 $a cello $n 1 $s 4 $2 lcmpt

19 382 example (complicated) Medium of performance: clarinet (doubling castanets) and oboe (doubling finger snapping) 382 01 $a clarinet $n 1 $d castanets $n 1 $a oboe $n 1 $d finger snapping $n 1 $s 2 $2 lcmpt +

20 382 example (bonkers) Medium of performance: soprano soloist accompanied by flute (doubling penny whistle), toy piano (or celesta), and handbell choir. 382 01 $b soprano voice $n 1 $a flute $n 1 $d penny whistle $n 1 $a toy piano $n 1 $p celesta $n 1 $a handbell choir $2 lcmpt + or

21 Bi-level examples (1) Medium of performance: flute choir (piccolo, 4 flutes, alto flute, and bass flute) 382 01 $a flute choir $2 lcmpt 382 01 $a piccolo $n 1 $a flute $n 4 $a alto flute $n 1 $a bass flute $n 1 $s 7 $2 lcmpt

22 Bi-level examples (2) Medium of performance: 2-6 violins 382 01 $a violin $n 2 $s 2 $2 lcmpt 382 01 $a violin $n 3 $s 3 $2 lcmpt 382 01 $a violin $n 4 $s 4 $2 lcmpt 382 01 $a violin $n 5 $s 5 $2 lcmpt 382 01 $a violin $n 6 $s 6 $2 lcmpt 382 01 $a violin ensemble $2 lcmpt +??

23 Back to those LCSH examples 650 #0 $a Concertos (Piano) 382 01 $b piano $n 1 $a orchestra $2 lcmpt 655 #7 $a Concertos. $2 lcgft* *Music LCGFT terms not released yet

24 650 #0 Quintets (Harpsichord, bassoon, flute, viola, cello) 382 01 $a harpsichord $n 1 $a bassoon $n 1 $a flute $n 1 $a viola $n 1 $a cello $n 1 $s 5 $2 lcmpt

25 650 #0 $a Sonatas (Flute and piano)OR 650 #0 $a Suites (Flute and piano)OR 650 #0 $a Flute and piano music 382 01 $a flute $n 1 $a piano $s 2 $2 lcmpt AND 655 #7 $a Sonatas. $2 lcgft* OR 655 #7 $a Suites. $2 lcgft* OR [No 655]

26 650 #0 Percussion ensemble. 382 01 $a timpani $n 1 $a triangle $n 1 $a snare drum $n 1 $a bongos $n 1 $s 4 $2 lcmpt

27 Still in flux  Piano 4 hands, etc.  Temporarily: 382 01 $a piano $n 2 $s 2 $v piano, 4 hands $2 lcmpt  Popular music  Sometimes it makes sense to include a 382 like: 382 01 $a electric guitar $n 1 $a guitar $n 1 $a electric bass $n 1 $a drum set $n 1 $s 4 $2 lcmpt … but usually it doesn’t.

28 Still in flux (continued)  Recording number of ensembles  $n only refers to the number of performers  Currently no good way to record a piece for two orchestras, etc.  MLA is looking into a new MARC subfield for number of ensembles  How will this work in BIBFRAME?

29 For now  Music catalogers are continuing to use LCSH terms in 650s  Encouraged to add 382s to bibliographic records as well  Adding 382s to authority records for musical works

30 In the future?  Retrospective conversion  Current subject headings have a wealth of information that can be converted to LCMPT vocabulary  New interfaces  Ability to plug in certain instruments and voices  Retrieve all musical works written for those media  Ability to facet by medium of performance

31 Have a new term?  The thesaurus has been launched, but maintenance will be ongoing  All proposals for new or changed terms should go through the SACO Music Funnel Project:  Currently proposed terms include:  agogo  glass harp  jhāñjh  prepared violin  ve ṇ u

32 The possibilities are endless Composers love to come up with new and strange ways to perform music. Deconstruction no. 2 – Songo-go For tenor voice, tam-tam, toy dart guns, golfer with ping pong balls, Walkman, and clock tower bells (Must be played at 4:00 p.m. to be timed correctly with the bells) (And also the tenor has to dance)
